JVC HM-100u becomes a 4k2k camera?

Maybe it is just an empty plastic housing at this stage:

I believe rhe new concept 4k2k will use the Falconbird engine of the PX10 which in a review JVC said that it had the capacity for 4k2K movies.

Save me the time, what is 4K2K?

"2K reference resolution is 2048×1536 pixels, whereas 4K reference resolution is 4096×3072 pixels. Nevertheless, 2K may also refer to resolutions like 2048×1556 (full-aperture), 2048×1152 (HDTV, 16:9 aspect ratio) or 2048×872 pixels (Cinemascope, 2.35:1 aspect ratio)"

4K:

I understand 4K or 2K, but what is 4K2K ?

Means that the camera will be able to record in both resolutions, but they do not say absolutely anything of when it will be available.

Thanks.
